Product Description

This is a utility module we found ourselves always needing and using. The three well spaced knobs can act as active attenuators, attenuverters (bipolar) and inverting attenuators depending on the setting of the three-position switches.

Each input is normalled to a DC voltage selectable via jumpers for each channel to be 5 v or 10 v. With nothing plugged into the jacks, each knob controls a voltage amount. So if the rear jumper for channel a was set to 5 v then the knob a would control the following ranges on output a: position 1: 0 to – 5 v, position 2: -5 to +5 v, and position 3: 0 to +5 v

skiff friendly (single pcb)

3 modes for each channel

5/10 v normalling to inputs

with external signals it acts as active/buffered attenuator/attenuverter/inverter
